Downlink Packet Error Rate tests (allowed 5% PER)

Cryptography tests

Receive Window test (1st and 2nd)

Handling of sequence number

Device Status Request test

Add/Modify channel tests

Confirmed/Unconfirmed uplink/downlink test

Check uplink frequencies

Since m/o September also Radiation Performance testing can be offered.

The
report that IMST provides as the output from LoRaWAN Radiation
Performance measurement gives antenna diagrams showing the minimum and
maximum values for the TRP (Total Radiated Power) and TIS (Total
Isotropic Sensitivity). Based on these figures, a network operator can
grade devices and ensure a good and smooth network availability and
performance. Within development these measurements would help
manufacturer to improve their designs.

The certification process in general is as follows:

LoRa® Certification Overview

The
LoRaWAN™ Certification Program provides assurance to end customers that
their application-specific end devices will operate on any LoRaWAN
network. The scope of the Certification Program confirms that the end
device meets the functional requirements of the LoRaWAN protocol
specification. The program includes a suite of tests that are specified
in the LoRa Alliance End Device Certification Requirements document*.

Device
manufacturers must be a member the LoRa Alliance to be LoRa Certified
and must use one of the accredited LoRa Certification test houses to do
the functional protocol testing. Upon completion of the tests, the
results will be listed on the LoRa Alliance website, and upon compliance
a LoRa Certification certificate will be issued by the LoRa Alliance.
